Define a color as transparent

[Daveed]

Hi!

I got a problem: I want to define a color in a PNG-Image as transparent. I'm able to do that with Word or PHP, but I don't challenge it to define a color as transparent on Paint.NET.

Could anybody help?

Thanks,

David

Just select the area you want to be transparent and press the delete key.

You will see a "checkerboard" pattern where the transparent areas are located.

Save your file as PNG and your transparent area will be transparent.

Shift+Magic Wand along with a low Tolerance setting allows you to select a specific color throughout the entire image.

Thanks!!

But is there any way to select an area with the same color (like the fill-tool, with the difference, that it selects instead of fill)?

Yes, the magic wand combined with the threshold.

Here, I've circled the magic wand tool in red:

If you want just that specific color, put the tolerance bar down to 0%.

TinSoldiert: Works perfectly! Thanks!

usedHONDA: When I put the tolerance bar down to 0%, what do I do then?
